IMPROVEMENTIN COMBINED SEEDER AND cuLT|vAToR..

Specification forming part of LettersPatent No. l94,757,. dated August28 1877; application filed i i Julyi5, 1877.

Toall whom it may concern:

Be it known-that I, ADAM Bareville, in the county of Lancaster audEState of Pennsylvania have invented certain .new and useful Improvementsin a Combined Seeder and Cultivator, of which the followiu g is aspecification that will enable those skilled in the art to make and usemy' invention, reference being had to the accompanying drawlogs.

The object of my invention is to improve the construction of that classof machines which, by an alternation of appliances, serve, respectively,to seed and afterward to cultivate grain.

My invention consists in the construction and arrangement of the deviceshereinafter specifically described, and definitely set forth in myclaims.

In the accompanying drawings, Figure l is a plan view of my combinedseeder and-cultivator, with portions of the seed'box and crossbeamsbroken away to show the parts lying under them more fully. Fig. 2 is avertical longitudinal section on the line 11 of Fig. 1.

Fig. 3 is a vertical central section through one of the seed-boots. Fig.4 is a rear elevation of the same- Figs. 5 and 6 are views, inelevation, of one form of a scarifying cultivatortooth; and Figs. 7and-8 are similar views of detachable cultivator-teeth employed when themachine is used as a cultivator.

A indicates the main frame; B, the wheels; 0, the seed-box, and D theboots or droppers, E indicates a lifting-beam pivoted to the side piecesof the main frame, and provided with a handle, F, and lifting-chains G,secured, at their lower ends, to the cultivator-teeth or the boots, asthe case may be. The boots are detachably secured on the rear ends ofthe drag-bars H, which are pivoted to the front portion of the mainframe. I provide the boots with furrowing-blades or teeth I, and withspreaders or distributors K. These distributers are secured to the frontsides of the interiors of the boots, passing through and being rivetedto secure the furrowing-blades in place. They form V-shaped rearwardprojections, against which the seed strikes in its descent, and isspread into the trenches formed by the teeth.

B. GEOFF, of;

It is essential that the boots be held rigidly in place and at uniformdistances apart. To accomplish this object I provide across-bar, L,through which pass hooksl, that clasp the drag-bars and prevent lateralmovement. The boots are provided with ears projecting in front, andclasping the rear ends of the drag-bars. These ears and the ends of thedrag-bars are provided with bolt-holes, so that the boots may beadjusted to vary their pitch.

When it is desired to use the machine for cultivating, the boots areusually removed and cultivatonteeth, provided with similar ears andbolt-holes, are substituted for them, and connected with thelifting-chains and drag-bars. It is obvious that the boots, with theirfurrowing-blades or teeth, mightbe used to cultivate, if desired, but Iprefer to remove them and replace them with cultivator-teeth, such asshown in Figs. 7 and 8. As the rows of grain are usually so neartogether that they would be in danger of being covered by the earththrown by the cultivator-teeth unless some means of prevention wereprovided, I therefore employ the protectors M between the teeth toshield the grain. These protectors I prefer to form V-shaped, and Iconnect them, by means of pivoted arms, to the dragbars or to the frontof the main frame. If desired, a detachable cross-bar, N, as shown indotted lines, may be provided and secured in place by a bolt at eachend, to which crossbar the protector-rods maybe hinged. The detachablecross-bar may be secured by its two end bolts either to the main frameor to the outside drag-bars. When it is used it will not be necessary tounhinge the protectorrods, in order to remove the protectors from themachine, but will only be necessary .to detach the cross-bar, when itand the protectors'can be removed together. The protectors are, ofcourse, only used for cultivating, and may be detached and removed fordrilling.

In order that the protectors, which ride lightly over the rows of grain,may be raised simultaneously with the cultivator-teeth for turningaround, or whenever desirable, I provide a lifting-bar, O, which Isuspend from.

the rigid cross-bar L by detachable screwrods P, or by any othersuitable means. If desired, a connecting-strap, B, may be secured alongthe edges of the protectors at their rear ends, in order to prevent;them from swaying from side to side, as shown in dotted lines.

In order to form a cultivator-tooth that can be readily attached to theends of the dragbars in place of the boot, I provide an ear orprojection on each side of the shank, as shown in Figs. 7 and 8, havingsuitable holes for attachment and adjustment upon the end of thedrag-bar. I also form a peculiar cultivatortooth of three parts orprongs, the two outside ones being provided with ears or projections asabove described, and the center one constituting at once a shank forsupport. ing the ears and a middle prong. This form of tooth is usefulfor harrowing or scarifyin g the soil when too dry or hard for the useof the ordinary tooth or blade.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The combination of the series of detach able andvertically-oscillating shields or pro tectors with the series ofcultivator-teeth, and the frame supporting both, and the liftingmechanism, by means of which the whole can be raised up by the operatorat will, substantially as described. I

2. The combination of the rigid cross-bar, the adjustablelifting-bar,the adjustable screwrods, and the drag-bar hooks, constituting the framefor rigidly securing the seedingboots and cultivatorteeth at a uniformand proper distance apart, and for lifting the shields, substantially asdescribed.

3. The detachable cross-bar, in combination with the pivoted rods andthe shields, substantially as described.

In testimony whereof I have hereunto subscribed my name.
